The SureFire SF18350 is a 3.7V lithium-ion cell with a built-in Micro-USB port, so it charges from any USB source without a separate charger. Its 1100 mAh capacity and 8A max discharge suit SureFire's 18350-compatible lights, and the integrated charge indicator shows status at a glance. It is a convenience part for people already in the SureFire ecosystem, not a high-capacity cell. Rivals such as KeepPower and Efest 18350s typically offer higher capacity but need an external charger.
